`
`
`
`I, Henry Grabowski, hereby declare as follows:
`
`Introduction
`
`I am over the age of eighteen (18) and otherwise competent to make this
`
`I.
`1.
`
`declaration.
`
`2.
`
`I understand that the Patent Trial and Appeal Board has granted Argentum
`
`Pharmaceuticals LLC’s (“Argentum”) petition to institute this Inter Partes Review
`
`(“IPR”) regarding claims 1–28 of United States Patent No. 8,268,299 (the “’299
`
`patent”) on obviousness grounds.
`
`A. Qualifications
`I am currently Professor Emeritus of Economics and the Director of the
`
`3.
`
`Program in Pharmaceuticals and Health Economics at Duke University. I received
`
`my Bachelor of Science degree in Engineering Physics from Lehigh University in
`
`1962. In 1967, I obtained a doctorate in Economics from Princeton
`
`University. My academic and research specialties are in the pharmaceutical
`
`industry—health economics, economics of innovation, and government regulation.
`
`4.
`
`I have studied the economics of the pharmaceutical industry over much of
`
`my career, and I have published numerous articles and books on this industry. I
`
`created a graduate course at Duke on economics and policy issues in the
`
`pharmaceutical industry. Under a series of grants from the National Science
`
`Foundation, I have examined the economics of pharmaceutical research and
`
`
`
`3
`
`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`development (“R&D”) and the effect of various government policy actions on drug
`
`innovation. I have testified several times before Congressional committees in the
`
`United States on pharmaceutical industry issues. For example, since 1994, I have
`
`testified on issues involving effective patent life and generic competition in
`
`pharmaceuticals, generic biologics, the Clinton Administration’s health reform
`
`legislation, and the federal government’s policy toward children’s vaccines.
`
`5.
`
`I have been an advisor and consultant to the National Academy of Sciences,
`
`Institute of Medicine, Federal Trade Commission, General Accounting Office, and
`
`Office of Technology Assessment. I have also held visiting scholar appointments
`
`at the International Institute of Management in Berlin, Germany, Health Care
`
`Financing Administration in Washington, D.C., the Office of Health Economics in
`
`London, and the Centre for Medicines Research in London. Until its acquisition
`
`by Gilead Sciences in 2003, I served on the Board of Directors of Triangle
`
`Pharmaceuticals, Inc., a development-stage company that specialized in antiviral
`
`drug therapies.
`
`6.
`
`I have done extensive research on the economics of competition in the
`
`pharmaceutical industry, including the role of patents and the importance of
`
`R&D. I have also performed several studies on pharmaceutical R&D costs and
`
`profits. The Congressional Budget Office has used my work in this regard to
`
`analyze the effects of the Drug Price Competition and Patent Term Restoration Act
`
`
`
`4
`
`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`(“Hatch-Waxman Act”) on R&D returns and to analyze the proposed changes
`
`associated with the Health Security Act of 1993.
`
`7.
`
`Exhibit 2030 is a copy of my curriculum vitae, which includes a more
`
`detailed description of my education and professional experience, as well as a list
`
`of my publications from the last forty years.
`
`B. Assignment
`I have been retained by Williams & Connolly LLP on behalf of Alcon
`
`8.
`
`Research, Ltd. (“Alcon”) to serve as an expert witness in this action.
`
`9.
`
`In particular, I have been asked to opine on whether Alcon’s drug,
`
`TRAVATAN Z®, is a commercial success, and if so, to address the factors
`
`underlying its commercial success, including whether there is a nexus between its
`
`commercial success and the features of the claimed invention. I have also been
`
`asked to opine on whether Alcon’s promotional activities for TRAVATAN Z® are
`
`in line with that of other products in the same therapeutic category.
`
`10.
`
`In connection with the opinions and conclusions contained within this
`
`declaration, listed below are the documents that I have reviewed and considered or
`
`created (based on data from IQVIA—formerly IMS Health—and Encuity
`
`Research, which I understand are being provided to Argentum). I have also relied
`
`on my training, my years of experience as an economist, my regular review and
`
`
`
`5
`
`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`knowledge of the economic literature, and presentations at academic and industry
`
`conferences.

`
`Summary of Opinions
`
`C.
`14. Based on my research and analyses summarized in this declaration, I
`
`conclude that TRAVATAN Z® has achieved commercial success in the U.S. I also
`
`conclude that there is a nexus between the commercial success of TRAVATAN Z®
`
`and its characteristics that embody inventions claimed by the patent at issue.
`
`15. The success of TRAVATAN Z® is demonstrated by its levels of and growth
`
`in dollar sales, units, prescriptions, and share in the United States. According to
`
`IQVIA data, since its launch in October 2006 through October 2017, TRAVATAN
`
`Z® has been prescribed 27.6 million times in the United States. Over this time
`
`period, the cumulative dollar sales of TRAVATAN Z® were $4.2 billion. The
`
`success of TRAVATAN Z® is further evidenced by the fact that it has quickly
`
`become one of the best-selling and most-prescribed drugs in its therapeutic
`
`
`
`14
`
`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`category and maintained a prominent position despite having to compete with
`
`alternative treatment options, including generic drugs.
`
`16.
`
`I understand that the claims of the ’299 patent at issue here describe self-
`
`preserved aqueous compositions, and in particular, cover compositions with a
`
`preservative system that is used by TRAVATAN Z® but not by any competing
`
`drug. The commercial success of TRAVATAN Z® is explained by what I
`
`understand to be the benefits of the claimed compositions with this preservative
`
`system as compared to other drug formulations that use conventional preservatives
`
`and are thus more likely to lead to ocular surface damage. This is demonstrated by
`
`the fact that TRAVATAN Z® has outperformed its predecessor drug,
`
`TRAVATAN®, which I understand was not self-preserved and did not use the
`
`claimed invention. This is further demonstrated by the fact that TRAVATAN Z®
`
`has continued to be a commercial success despite the availability of other
`
`therapeutic alternatives, which I understand are similarly efficacious and at least
`
`some of which can be purchased at lower cost, but are also not self-preserved and
`
`do not use the claimed invention. Based on this and other evidence, it is my
`
`opinion that there is a nexus between the commercial success of TRAVATAN Z®
`
`and the claimed invention.
`
`17.
`
`In determining whether there is a nexus between TRAVATAN Z®’s
`
`commercial success and the claimed invention, I have also evaluated whether the
`
`
`
`15
`
`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`drug’s commercial success could be attributed to other factors, such as excessive
`
`promotion. In my opinion, TRAVATAN Z®’s commercial success has not been
`
`the result of excessive marketing or the provision of coupons to patients. The
`
`extent of marketing expenditures for TRAVATAN Z® is consistent with that of
`
`other competing products, especially considering that TRAVATAN Z® was
`
`launched in a crowded market where other available treatment options had been
`
`promoted for many years prior to TRAVATAN Z®’s launch. Similarly, the extent
`
`to which Alcon has been offering copayment coupons to patients for TRAVATAN
`
`Z® is comparable to that of manufacturers selling other drugs in the same
`
`therapeutic category. Further, copayment coupons are unlikely to drive the
`
`demand for TRAVATAN Z® since a large number of TRAVATAN Z® patients are
`
`prohibited from using such coupons.
`
`II.
`18.
`
`Treatment of Glaucoma with Ophthalmic Prostaglandin Analog Drugs
`
`I have reviewed the declaration of Dr. Richard Parrish and rely on his
`
`opinions herein. Based on my review of his declaration, I understand that open-
`
`angle glaucoma is a disease characterized by chronic, progressive damage to the
`
`optic nerve, usually associated with elevated intraocular pressure (“IOP”). I also
`
`understand that the prevalence of glaucoma is directly related to age—as
`
`individuals age, they are more likely to develop glaucoma.
`
`
`
`16
`
`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`19.
`
`I understand that the most common type of medication used to treat
`
`glaucoma patients with elevated IOP are a class of drugs known as prostaglandin
`
`analogs (“PGAs”). TRAVATAN Z® (travoprost) was approved by the U.S. Food
`
`and Drug Administration (“FDA”) on September 21, 2006.4 I understand that
`
`TRAVATAN Z® is a PGA. Alcon launched TRAVATAN Z® in October 2006.5
`
`TRAVATAN Z® is indicated for the “reduction of elevated intraocular pressure in
`
`patients with open angle glaucoma or ocular hypertension.”6
`
`20. According to Dr. Parrish, the PGAs available in 2006 in the U.S. included
`
`TRAVATAN® (travoprost), XALATAN® (latanoprost), and LUMIGAN® 0.03%
`
`(bimatoprost). In addition to TRAVATAN Z®, branded PGAs available today
`
`include: XALATAN®, LUMIGAN® (reformulated as 0.01%), and ZIOPTAN®
`
`(tafluprost). Generic latanoprost, bimatoprost (0.03%), and travoprost are also
`
`now available. I understand from counsel that generic travoprost became available
`
`in 2013. I understand from Dr. Parrish that TRAVATAN Z® is a successor product
`
`
`4 Ex. 2060.
`
`5 Ex. 2061, 53.
`
`6 Ex. 2062.
`
`
`
`17
`
`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`to TRAVATAN®: it has the same active ingredient (travoprost), but a different
`
`preservative system. Exhibit 2040 summarizes the various PGAs on the market.7
`
`21. My understanding from Dr. Parrish is that although other, non-PGA
`
`treatments are available for the long-term treatment of glaucoma, they are not
`
`comparable to PGAs, are not considered to be therapeutic alternatives to
`
`TRAVATAN Z®, are generally not as efficacious as PGAs in lowering IOP, and
`
`are generally prescribed with far less frequency than PGAs. I understand that these
`
`categories of drugs include beta-blockers, alpha-2 agonists, topical carbonic
`
`anhydrase inhibitors, and combination drugs. For purposes of this report and in
`
`accordance with Dr. Parrish’s opinion, I have analyzed TRAVATAN Z®’s
`
`performance as compared to that of other PGAs approved for treatment of open-
`
`angle glaucoma and ocular hypertension.
`
`
`7 Based on Dr. Parrish’s declaration, it is my understanding that ZIOPTAN™ is
`
`not a comparable drug to the other PGAs. I further understand that RESCULA® is
`
`a prostanoid, and while it has some characteristics which are similar to PGAs, it is
`
`not technically a PGA. Further, RESCULA® was discontinued in early 2015. (Ex.
`
`2063, 39.) In this declaration, I have considered all the drugs listed in Exhibit
`
`2040, including ZIOPTAN™ and RESCULA®. However, excluding these two
`
`drugs from my analysis would not affect my conclusions.
`
`
`
`18
`
`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`22. Based on my review of Dr. Parrish’s declaration, I understand that all the
`
`PGAs currently on the market—including TRAVATAN Z®, XALATAN®,
`
`LUMIGAN®, and generic latanoprost, travoprost, and bimatoprost—are similar in
`
`efficacy at treating elevated IOP. I further understand that except for TRAVATAN
`
`Z®, all of these drugs contain benzalkonium chloride (“BAK”) as a preservative.8
`
`23. According to Dr. Parrish, the long-term use of BAK exacerbates the
`
`symptoms associated with various forms of ocular surface disease (“OSD”). I
`
`understand that OSD is a significant concern among clinicians, and that for patients
`
`with OSD symptoms, the use of ophthalmic formulations without BAK is
`
`preferred. I understand that because TRAVATAN Z® does not contain BAK, it has
`
`a less toxic effect on the ocular surface, leading to decreased incidence of
`
`symptoms of OSD among patients taking TRAVATAN Z® in comparison to
`
`patients taking other PGAs. Per Dr. Parrish, I understand that even though
`
`TRAVATAN Z® is more expensive than some other medical treatment options, it
`
`is a first-line treatment for glaucoma patients with symptoms of OSD because it
`
`has reduced potential for exacerbation of those symptoms.
`
`
`8 I understand from counsel that the absence of BAK from TRAVATAN Z®’s
`
`formulation is a result of its use of the claimed invention.

`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`III. TRAVATAN Z® Is a Commercial Success
`24. There are several indicators that can be used to determine whether a product
`
`has achieved commercial success. The indicators for the success of a patented
`
`drug product include levels of and growth trends in dollar sales, prescriptions, and
`
`units of the product, as well as its performance relative to competing products
`
`(typically measured in terms of share of sales, prescriptions, or units). A product
`
`does not have to satisfy all of these indicators to be considered commercially
`
`successful. Rather, each indicator can demonstrate the commercial success of the
`
`product, either alone or in conjunction with other indicators.
`
`25. My analyses below demonstrate that TRAVATAN Z® is a commercially
`
`successful drug. Since its launch in 2006 through October 2017, TRAVATAN Z®
`
`has been prescribed 27.6 million times in the United States. Over this time period,
`
`the cumulative dollar sales of TRAVATAN Z® were $4.2 billion.
`
`26. Exhibit 2041 graphs annual U.S. wholesale dollar sales for TRAVATAN Z®.
`
`TRAVATAN Z® reached sales of almost $65 million in 2007, its first full calendar
`
`year on the market. TRAVATAN Z®’s sales generally increased over the
`
`following years, approaching $554 million in 2016, the last full calendar year for
`
`which data are available. The level of sales in 2016 represents an approximately
`
`8.6-fold increase over the sales in 2007 and translates into an annual growth rate of
`
`26.9 percent over this period. The data for the first ten months of 2017 indicate a
`
`
`
`20
`
`Case IPR2017-01053
`Patent 8,268,299
`
`
`
`similarly strong performance in the current year. TRAVATAN Z® demonstrated
`
`this strong sales performance despite being a late entrant in its therapeutic category
`
`and facing competition not only from other branded PG
